iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
This document summarizes a study on effectively beneficiating low-grade iron ore through jigging. Jigging is investigated as a gravity separation technique using a Denver mineral jig and Harz jig. Variables like particle size, water velocity, and amplitude are evaluated. Optimum recovery of 78.6% iron ore is achieved with a concentrate grade of 63.7% Fe when jigged at …
Present investigation includes the magnetizing roasting of low-grade iron ore fines followed by grinding and beneficiation using magnetic separation. The hematite iron ore used in the investigation contains 53.17% T …
Jigging is especially useful for low-grade iron ores, potentially creating saleable product from what would otherwise be mine waste. For example, Sishen Mine in South Africa has shown that lower-grade ROM (50–60% Fe) can be upgraded to a saleable 64% Fe product, greatly enhancing the resource base of the mine (Pretorius and Hoffmann, 2006).
In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others. The combination of spiral and multi …
The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional beneficiation …
